General Discussion

What will happen is that more insurance companies will pull out as climate change escalates. Eventually a tipping point will be reached and a real estate crisis larger than any we've ever seen will occur. When the realization that large parts of the planet will be unliveable, not just in the far future but in a matter of decades, finally clicks in the minds of the general population, there will be a population exodus from these areas, and trillions of dollars in land, houses, and commercial property will be essentially worthless. The smart ones will sell early, and the dumb ones will be left broke, holding mortgages worth pennies on the dollar. Seaside neighborhoods once worth millions will become slums, and inland areas will gentrify.

And there won't be a government program large enough to stop it. Even a half-hearted attempt would bankrupt most nations, because the scale of the climate change disaster is unprecedented in human history. We've pushed the planet's climate too far, and it's too late to prevent catastrophe.
